*Specification* *Not yet!* *Summary* Expose measurement data regarding speculative loads (preloads, prefetch and prerenders) as part of the "pagehide" event. That would enable developers to measure the efficacy of various speculative loading strategies and adapt them accordingly. *Blink component* Blink>PerformanceAPIs <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EPerformanceAPIs%22> *Web Feature ID* Missing feature *Motivation* Modern web applications can use speculative loading techniques to improve navigation performance. However, developers currently lack visibility into whether these speculations were actually used, making it hard for them to deploy higher eagerness values than "conservative". Such values can result in wasted user bandwidth and server-side load, and currently developers have no way to weigh the trade-off between those and potential performance gains. This proposal addresses this by exposing information about used and unused speculative loads on page dismissal, enabling developers to measure speculation effectiveness and optimize their speculative load strategies, to pick the trade-off that's right for them. *Initial public proposal* https://github.com/WICG/proposals/issues/264 *Requires code in //chrome?* False *Tracking bug* https://issues.chromium.org/issues/481590676 *Estimated milestones* No milestones specified *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5118840377835520?gate=5117422031994880 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
